The BSM 140 DUAL is designed for use in situations where 2 batteries are used; for example in boats, campers and caravans. The Battery separator is a microprocessor controlled high capacity mechanical switch with vibration (i.e. motion) detection. Since every vehicle (EURO 5/6 engines) has its own vibration frequency and amplitude, the user can set the sensitivity of the BSM.
